Bravo Environmental NW is a proud part­ner of NASSCO (the National Asso­ci­a­tion of Sewer Ser­vice Com­pa­nies).  We offer train­ing, cer­ti­fi­ca­tion, and recer­ti­fi­ca­tion classes for PACP, MACP, and LACP (Pipe Assess­ment Cer­ti­fi­ca­tion Pro­gram, Man­hole Assess­ment Cer­ti­fi­ca­tion Pro­gram, and Lat­eral Assess­ment Cer­ti­fi­ca­tion Program).

The Pipeline Assess­ment Cer­ti­fi­ca­tion Pro­gram (PACP) is a highly-​​acclaimed set of stan­dards and has been widely used through­out North Amer­ica since 2002.  PACP utilitizes four “fam­i­lies” or groups of codes to describe fea­tures, defects and con­di­tions in under­ground pipes.  The four groups of obser­va­tions are:

Struc­tural Defects: such as cracks, frac­tures, or bro­ken sec­tions of pipe.

Oper­a­tion & Main­te­nance (O & M) Defects: such as grease and debris deposits, or root infiltration.

Con­struc­tion Fea­tures: such as pipe material changes, access points, or the loca­tion and type of tap (ser­vice) connections.

Mis­cel­la­neous Observations: such as spe­cial con­di­tions of the sur­vey (cam­era under­wa­ter) or the pipe’s water level(s).

Why Use PACP?

Since the 1980s and 90s, CCTV and dig­i­tal scan­ning cam­eras have been widely used to inspect the con­di­tion of under­ground pipes.  Apply­ing PACP obser­va­tions to iden­tify defects and con­di­tions in the pipe not only ren­ders a detailed report fol­lowing indus­try stan­dards of qual­ity and objec­tiv­ity, but also enables a numer­i­cal Con­di­tion Rat­ing (0 through 5) for each pipe segment sur­veyed, allow­ing those in asset man­agement and engi­neering to quickly pri­or­i­tize main­te­nance, clean­ing, and reha­bil­i­ta­tion projects, as well as long-​​term cap­i­tal improve­ment strate­gies.  A PACP Quick Score is also avail­able, which describes how many of each kind of defect (and its sever­ity) was iden­ti­fied during the survey – allow­ing for more detail and context than just the Con­di­tion Rat­ing, while still pro­vid­ing sim­plic­ity and effi­ciency.  In other words, PACP, unlike many other stan­dards for pipe con­di­tion report­ing, uses numer­i­cal scor­ing on the back-​​end to give each obser­va­tion an impar­tial value, used to pro­duce an over­ral rating.

How Do I Get My PACP Certification?

Bravo Environmental NW reg­u­larly holds PACP cer­ti­fi­ca­tion courses.  PACP cer­ti­fi­ca­tion is a 2-​​day (16-​​18 hours total) class where the NASSCO mate­r­ial is pre­sented along­side exam­ple pho­tos and video from pipe inspec­tion data showing con­di­tions and defects in sew­ers.  The class includes dis­cus­sions about the factors which cause pipes to deteriorate, a history of underground construction and maintenance, how best to cal­i­brate, set up, and oper­ate a sewer inspec­tion cam­era, as well as review of all the NASSCO mate­r­ial, plus some infor­mal quizzes on the major sec­tions.  This is fol­lowed by a final test on the sec­ond day.  An 85% score or bet­ter earns a PACP cer­ti­fi­ca­tion, which is good for 3 years.

What are MACP and LACP?

MACP stands for Man­hole Assess­ment Cer­ti­fi­ca­tion Pro­gram, and LACP stands for Lat­eral Assess­ment Cer­ti­fi­ca­tion Pro­gram.  They are both exten­sions of PACP cer­ti­fi­ca­tion, and are offered as add-​​ons to those who also hold PACPcer­ti­fi­ca­tion (PACP is a pre-​​requisite for man­holes and lat­er­als).  Typ­i­cally MACP & LACP cer­ti­fi­ca­tions are held in a sin­gle day, and can be included as the third day of a PACP train­ing course.

Man­hole Assess­ment Cer­ti­fi­ca­tion Program

NASSCO has devel­oped a pro­gram for report­ing defects and fea­tures of man­holes which adheres to the basic PACPfor­mat, while tak­ing into account that man­holes typ­i­cally are more com­plex struc­tures than pipes, and includes two sep­a­rate pro­to­cols for man­hole inspec­tion, depend­ing on the needs of the util­ity owner.  The Level 1 inspec­tion is a basic con­di­tion assess­ment of the man­hole (which does not require con­fined space entry or remote equip­ment), while the Level 2 inspec­tion fully doc­u­ments fea­tures, dimen­sions, and defects through­out the man­hole, and gen­er­ally requires remote equip­ment and/​or entry into the manhole.

Lat­eral Assess­ment Cer­ti­fi­ca­tion Program

Once PACP spread in use and pop­u­lar­ity, it became clear it would be sim­ple, and ben­e­fi­cial, to apply PACP (main­line pipe assess­ment) to sewer lat­er­als (also called side sew­ers).  The LACP con­tent addresses some of the key dif­fer­ences between lat­er­als and main­line pipes (pri­mar­ily the dif­fer­ent lat­eral fit­tings and access meth­ods), but very closely fol­lows PACP, and retains nearly all of the PACP obser­va­tion codes.  The LACP enables asset own­ers to address the con­di­tion and main­te­nance of the sewer lat­eral, in addi­tion to main­line pipes and manholes.
